Correlation Parlays

[tech]

A correlated parlay is when you parlay two events in which one of them is more likely to happen if the other one also happens.

For example, suppose a sportsbook offered bets on the weather on a given day where you could bet sunny/cloudy, rain/no rain, etc. A correlated parlay would be to parlay cloudy and rainy, since they are highly likely to happen at the same time.

Now think about all the times that can happen in sports. One common one is that in MLB, an under is more likely if the home team wins and an over is more likely if the road team wins.
